Transport of Pb 2+ was carried from acidic solution into alkaline stripping phase through tri‐ n ‐octylamine‐xylene‐polypropylene supported liquid membrane. The transport of Pb 2+ through the membrane was studied by varying the concentration of Pb 2+ and HNO 3 in feed solution, NaOH concentration in strip solution and TOA concentration in membrane phase. The flux data obtained has been used to study the stoichiometry of complex Pb(NO 3 ) n +2 (HNR 3 ) n . The supported liquid membrane (SLM) has been found stable for 10 runs with 24 h between each run. This SLM has been used effectively to extract lead ions along with chromium, copper and zinc ions from aqueous acidic leached solution of paint and industrial effluents. © 2012 Canadian Society for Chemical Engineering
